This invention relates to apparatus for elevating acids and otherliquids and more particularly liquids of a corrosive nature where emoving parts such as pump pistons in contact r wit-h the liquid areobjectionable and a source of constant trouble. The object of theinvention is to provide an apparatus which will 2 act in eifect like apump, using compressed air, or other gases under pressure, or steam l asthe operating medium.

The invention consists broadly in the provision of one or more.containers having inlet and discharge openings and means whereby eachcontainer is alternately filled with liquid and supplied with gas underpressure so as to force out the liquid through the discharge openings.

Some of the forms which the invention may take are illustrated in theaccompanying drawings in which Fig. 1 shows diagrammatically a verticalsection through one embodiment of the invention.

V t Fig, 2 shows a vertical section through the Z 'junction of thedischarge pipes in another embodiment of the invention.

In the construction shown in Fig. ltwo cylindrical, or other suitablyshaped containers 1 and 2 of lead, ebonite, porcelain or other suitablematerial are immersed in the liquid to be elevated and are provided withinlet valves so arranged that when pressure is applied to the inside ofeither container its 3 {valve automatically closes. These valves mayconsist of rubber balls 3 and 4 resting on seatings 5 and 6 made fromthe same material as the container, or of glass balls resting on rubberseatings, or any other suitable in combination. Guards 7 and 8 areprovided to prevent the balls floating off.

Each container is provided with a discharge pipe 9 and 10, extendingfrom the 2 lowest point of each container upwards through thecontainers, or outside them, to

thedelivery pipe 11 into which it is dr'efsired to lift the liquid.

Pressure pipes: highest point of each container and are con nected toopposite sides of a two way control valve or cock one positionof whichapplies pressure to the inside of one container and at the same timeconnects the inside of the other to the atmosphere and vicervers'a' whenw the'control valve is moved tothe other position. c J The body of thecontrol valvejfis formed in two portions 14 and 15 and is in commu-'nication, through the pipes12 and 13, with 12 and 13 are fitted thecontainers 1 and 2 and,"through a ipe 6o 16, with a s'ourceof compressed:air or other gas under ressure. Arodf17'is slidably mounted withinthefbody of thevalve'and' carries aball '18 of rubber or other suitablematerial which is secured thereon-between a pair of tubularfsleeves 19and 20 which are provided with longitudinal slots 21' and '22. The rod17 also carries rubber washers 23 and'2t which are secured by metalwashers 25 and 26 andnuts 27 and 28. p 1 'v When, the valve is in theposition shown in the figure the rubber ball 18 cuts ofi'the supply ofcompressed air, delivered through the pipe 16, from the pipe 13 and thusfrom the container 1. The container 1'1 is however in communication,through the, pipe 13 andl the slots 21, with the atmosphere. The pressure of the liquid will thus lift theball 3 and the container will fillwith liquid.

At the same time the container 2 is 'in comsource of compressed airthrough the pipes 12 and 16. The slots 22 do not extend to theatmosphere and the bearing of the rod 17 is furthersealed' by the"munication with the rubber washer 24; Any liquid there maybe in thecontainer will thus be rorced up the discharge pipe 10 into the. pipe11. When all the liquid from the container 2 has been forced through thedischarge pipe into the delivery pipe the sudden acceleration of air 9PATE T] I to a check valve,

turn valve controlling in the system moves the ball valve 18 to theright cutting off the supply of compressed air from the container 2 andopening it to the atmosphere. At the same time the container 1 is shutoff from the atmosphere and sup plied with compressed air through thepipe 13, so dischargingthe contents of the container 1 through the pipe9 while the conta-iner 2 is being filled.

Instead of using two rising pipes both discharge pipes 7 9 and 10 may beconnected a vertical section through which is shown, inFigure 2.

The discharge pipes 9 and 10 open into the space within the body 30, andthe opening of either of them may? be sealed by the rubber ball 31. Theinterior of the valve is in com munication with a vertical delivery pipe11. A guard 32 is provided at the mouth of this pipe to prevent the ball31 from floating off.

.When the liquid is being discharged from one of the containers throughthe pipe 9 the ball is forced tothe right,sealing the pipe 10and-preventing the liquid from flowing back intotheother container. Allthe liquid is thusforced upthe delivery pipe 11. When all the liquid.hasbeen forced out of. this pipe theair supply control valve operates asabove describedv and. liquid is then forced from the other containerthrough the discharge pipe 10; the ball 31 is forced to the left andseals the opening of the pipe 9. All the. liquid is thus. forced. up thepipe 11.

What I claim and desire to secure by Let- Patent is 1 Apparatus forelevating liquids comprising a pairof containers adapted to be immersed.in the liquid to be elevated, an inlet to each of said containers, anautomatic nonreturnvalve controlling each of said inlets, dischargepipesleading from each of said containers to a common discharge main,separate pipes for conducting elastic fluid pressure to each of said.containers, a main pipe conducting elastic fluid pressure from a-sourceof supply to each of. said separate pipes, a valve chest to and fromwhich said main. and separate pipes lead, and having ports towhich saidseparate pipes arecoua slidable-spindle on which said. valve is fixedlymounted, said spindle passing, longitudinally through said chest and.operating. to close each of said ports alternately, a sleevevalvemounted upon each endofsaidslidablespindle so-as to move together withthe ball valve andhaving ports which connect each of the separate pipesto atmosphereby backpressure when said ball valve operates to shutofl'the supply 'of elastic .pressureto such pipe.

2.1 Apparatus for elevating liquids comprising a pair of containersadapted-to be immersed in theliquid'to be elevated and each having aninlet, an automatic non-reeach of said inlets, a

common discharge main, discharge pipes leading from each of saidcontainers to said common discharge main, a main pipe for conductingelastic fluid pressure from a source of supply to each of said separatepipes, and an oscillating valve member between said main and separatepipes and directly exposed to the flow of elastic fluid, said valvemember operating to connect each of said separate pipes alternately tothe atmosphere and the main pipe and being actuated solely by theacceleration of the elastic fluid flowing past it. In witness whereof Iaflix my signature.
